Main purpose: this machine use power gasoline engines (original import), start and operation convenient), control simple and reliable, equipped with man-made diamond core drill bit,the size for customers to choose , Mainly used for highways, airports, ports, docks, DAMS and other concrete, asphalt pavement, this function testing equipment 400-700 cm for depth, mainly in the highway ,as thefoundation of get off concrete, limestone to test compressive strength and rupture
20 HZ type concrete drilling core machine
This machine for HZ series diamond engineering is one of the drill. The gasoline engine as power (Honda) starting fast, simple operation, reliable operation, and suitable for no power sites and large diameter drilling engineering.
First, the main use:
The engineering drilling machine of 20 type by using high-speed cutting technology, and thin wall diamond bit form a complete set, is widely used in engineering construction, municipal engineering, equipment installation engineering and construction quality inspection engineering and other areas of drilling and coring.
1, in highway, airport, port, DAMS and other concrete, asphalt pavement, limestone basis core on compressive and bending test.
2, installation of large mechanical equipment drill anchor bolt hole.
3, installation bridge armrest and traffic safety protective barrier drilling.
Second, the main features:
1, with double column structure, bolt follow up way, good stability, simple operation effort. Equipped with road wheel, convenient to move.
2, adopting high speed cutting technology and thin wall diamond bit form a complete set, drilling cutting high strength reinforced concrete, high drilling efficiency, hole location accurate, hole wall smooth, good pore forming quality, core sample complete smooth, small vibration, no damage to buildings.
Three, main technical parameters:
1, maximum hole size: 200 mm
2, maximum drill hole depth: 700 mm
3, output revolution: 800-1200 revolution of/minutes and
4, power: 5.5 horsepower 9.0 horsepower (Honda petrol engine)
5, machine weight: 110 kilograms (5.5 horsepower) 150 kilograms (9 horsepower)
Four, operation process
1, preparation work before use
(1) add in 93 # unleaded gasoline and advanced lubricating oil, add how much oil according to oil scale scale for Quasi.
(2) in the post add lubricating oil, and rotating feed handle and output shaft, check the feed and rotary is flexible and reliable.
(3) ready to water
(4) check whether each part of the screw loose.
2, installation
Bit alignment hole location, the three road wheel move on, let base fall into the ground. Spile and concrete strength is not high, the rely on drill's own weight can have drill fixed, if dozen aperture is bigger, drill own weight can't hold drill, the chassis placed weight (such as sandbag, iron, concrete block, etc.) fixed or play two expansion bolt combined with pressure bar (such as channel steel, etc.) to fixed drill, drill fixed to firm, and shall not shake, otherwise drill empty operation can't normal.
3, opening
Above the work done, you can open hole operation, mount bit, start the engine (details see the engine user manual) the water inlet into the cask, buckets to improve to the water pump position, and then hand pinches balloon the water suction pump, pump water after bucket on the ground can. Throttle transferred to the largest, began to jiggle feed handle, bit slow in contact with the ground. Opening will definitely: first after water drilling, feed speed will slow, drill pressure to small. It is strictly prohibited to anhydrous operation, in order to avoid burned bit and water.
4, normal drilling in
When open hole drilling 2-3 mm deep, can turn into normal drilling, the feed pressure appropriately enlarging, normal drilling to definitely is: give into pressure must be moderate, is to keep uniform, encounter crude steel feed pressure to reduce. Do a listen to two look, listen to the voice of the machine is normal or not, see orifice whether return (take) water.
5, final hole
Arrived after required depth, can stop drill. Stop drilling requirement is: first close the machine off water, if deep hole, was not immediately lift drill and cut off the water supply, and want to use water punching a period of time, the purpose lies in the hole in the rock powder is rinsed clean, in case of rock powder precipitation lead to buried drill, cause core difficulties.
Five, the matters needing attention
1, when there is sticking, do not use forced starting machine way to eliminate sticking, and should adopt artificial methods (such as with extended move hand rotation bit) ruled out before rebooting the machine.
2, when core card in the bit inside, should immediately stop drilling, keep clear of in time. Clear, only allow use rubber hammer or soft sticks gently knock on bit steel body, repeated stroke can core clear out. It is strictly prohibited to use hammer knock bit or core, it is strictly prohibited to use iron from bit back into knock core, in order to avoid damage to core drill bit.
3, before the use should carefully read (gasoline engine user manual)
4, it is strictly prohibited to homework without water.
Six, repair and maintenance
1, core is completed, the proper site rub-up, dry, oil.
2, want to have the professional personnel responsible for use and maintenance, to maintain the normal use of the machine.
3, often check gasoline, oil, in case of short oil cause machine damage influence life.
4, machine long time use or using the multiple, should check again each place bolt have loose phenomenon, in case of influence and delay normal use.
5, such as machine long time not to use, should put the mechanization of the oil gas put net, in case carburetor immersion time is too long, the next is not easy to start.
Seven, common fault and eliminate
fault | reason | |
Gasoline engine oil at | 1, oil too much 2, oil into the combustion chamber
| 1, extraction of part of oil 2, unload spark plug, and then pull start handle, the oil completely discharge, superior spark plug start the engine idle to normal. |
Gasoline engine boring | 1, gasoline label less than 2, the choke valve closed | 1, change into grade gasoline 2, governor turning back, opened the choke |
The engine is not easy to start | Spark plug carbon too much 2, spark plug over old 3, choke not closed (when it's cold) | 1, clear spark plug 2, change new spark plug 3, closed choke
|
Core slow
| 1, bit a blunt 2, belt over old 3, belt loose 4, speed slow
| 1, change new bit 2, change new standard Angle bring 3, adjust taut band bolt 4, throttle set to high speed position |
